Caution

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on your computer.

You must have appropriate permissions to make changes to a registry key. To maintain security when making changes to a registry key for which you need administrative credentials, log in as a member of the Users group and run Regedit as an administrator by right-clicking the Regedit icon, clicking Run as, and clicking an account in the local Administrators group. The Regedit icon does not appear by default from the Start menu. To access the icon, open the Windows or WINNT folder on your computer.

Choosing Last Known Good Configuration provides a way to recover from problems such as a newly added driver that may be incorrect for your hardware. It does not solve problems caused by corrupted or missing drivers or files.

When you choose Last Known Good Configuration, Windows restores information in registry key HKLM\System\CurrentControlSet only. Any changes you have made in other registry keys remain.

Information about functional differences

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
